Hi.

I've been getting up and running with LPCXpresso (v5.0.12) and the LPC4357 using the mcb4357 evaluation board, LPC-Link programmer and LPCOpen platform.

Unfortunately i always get this error: "15: Target error from Commit Flash write" when trying to debug any of the single core USB examples. The basic blinky examples (both single core and dual core) work perfectly, however I can't get any of the usb examples to work.

The dual core usb mass storage example programs and starts the debug session fine but then always jumps immediatley into a hardfault so I can't get anywhere with that either.

I've read through the other posts and wiki entries on this error and have tried using an external 2A power supply, enabling vector catch and booting into the ISP bootloader. None of these has made any difference.

When attempting to program the board using the keyboard example and the flash tool i get a similar error and the following log:

I'd be very grateful for any help as I need to get this working asap as we need to decide on a new microcontroller platform for our new product range.
